=head1 SYNOPSIS
coalifornicus-linux B group base DN B user base DN B passwd file
B group file B shadow file [B output file prepend]

It should be pointed to where the users are stored in your LDAP directory.
=item B group file
This is the group file that will be used for generating group.ldif.
=item B passwd file
This is the passwd file to be used for generating the user.ldif.
=item B shadow file

generating user.ldif.
=item B output prepend
